p4 + svn + git

That might be too much, but let's ask anyway...

My company uses perforce.
I took a snapshot of some code checked out from perforce (a single
branch), that I imported into subversion, a while ago, and started
working with svn only. I have different Unix machines checking in /
out code code from the subversion server (with svn), and I'd like to
keep it this way (if possible).

I'm wondering if I could use git as a gateway between both systems, to
merge code in both direction (svn <-> perforce).

Is this possible, with the help of git-p4import, git-svn, and using
several branches ?

Thanks,
Benjamin.
